About EMISAT:
- Purpose:(1) It’s intended for electromagnetic spectrum measurement.(2) It’s been developed for monitoring radar network by India.
- Weight: 436 kg.
- Orbit location: 753 km altitude.
- Basis: EMISAT based on ISROs Indian Mini Satellite-2 (IMS-2) bus platform.
- Platform for different experiments:(1) After all the satellites are put into orbits, the fourth stage of the rocket will be propelled to a different elevation and will be used as a platform for different experiments by Indian institutions, including ISRO.(2) Indian Institute of Space Science (IISc) and the Radio Amateur Satellite Corporation are the other two institutions that will have their devices on the experimental platform.
- Difference from previous launch:(1) Normally the rocket engine is left redundant as space debris once the launch mission is over.(2) But ISRO uses it for such experiments for the second time in a series.(3)n During the last PSLV mission also it adopted the same innovative method.
PS4 Orbital Platform:
- Aim: To provide a microgravity environment for research organisations and academic institutes to perform experiments.
- Three payloads: In this mission, the PS4 hosts three payloads-(1) Automatic Identification System (AIS) from ISRO.(2) Automatic Packet Repeating System (APRS) from AMSAT (Radio Amateur Satellite Corporation).(3) India and Advanced Retarding Potential Analyzer for Ionospheric Studies (ARIS) from Indian Institute of Space Science and technology (IIST).
